Title:
BRAKING DEVICE AND SHIELDING DEVICE
Document Type and Number:
Japanese Patent JP2016017286
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a braking device that allows smooth switching among a plurality of braking mechanisms.SOLUTION: A braking device according to the present invention provides a braking torque to a drive shaft, and includes a first braking mechanism and a second braking mechanism. The first and the second braking mechanisms are configured such that a graph showing a relation between rotation speed and braking torque of an input shaft has an intersection, and a slant of the graph of the first braking mechanism at the intersection is larger than that of the graph of the second braking mechanism. Rotation of the drive shaft is conveyed to the input shaft of the first braking mechanism, and an output shaft of the first braking mechanism and the input shaft of the second braking mechanism rotate together.SELECTED DRAWING: Figure 1
